To find the perimeter of a rectangle, you can use the formula:
\[
\text{Perimeter} = 2 \times (\text{Length} + \text{Width})
\]
In this case, the length is 4.5 cm and the width is 9.5 cm. Substituting in the values:
\[
\text{Perimeter} = 2 \times (4.5 \, \text{cm} + 9.5 \, \text{cm}) = 2 \times (14 \, \text{cm}) = 28 \, \text{cm}
\]
The answer is **A. 28 cm**.
